To all whom z't may concern:

Be it known'that I,:Ronnn'r A. BAGNELL, a

- dling metals in molten form, suchfas may be adaptable for use infoundries and similar places to convey metal in molten form from thesource of supply to the placewhere it is to be used.

The molten metal discharged from the furnace of a smelter or the like isoften cast into so called pigs,-and for that purpose must be conveyedfrom the furnace to the pig molds. This is usually done by receiving thedischarge of the furnace in a suitable ladle, transporting the ladle tothe pig molds and discharging the metal into said molds. In some caseswhere conditions permit, the pig molds are located in close proximity tothe furnace. The metal is then discharged from the furnace and allowedto run into the molds. This arrangement necessitates the location of thepig molds very close to the discharge opening of the furnace and suchlocation is often inconvenient to other operations about the furnace.

One of the objects of this invention, therefore, is to provide a troughfor conveying the molten metal from the furnace to the molds, whichshall be capable of being easily assembled or dissembled, so that it maybe put in place when wanted and removed when not wanted.

Another object of this invention is to provide such a trou h which, whenit becomes choked with solidified metal, slag or the like, may bereadily cleaned of such obstructions.

Another object is to provide such a trough which shall be simple inconstruction, cheap to manufacture and simple to handle.

Further objects will appear from the following description taken inconnection with the accompanying drawing, in which:

Figure 1 represents a plan view of a trough embodying this invention;

Figure 2 represents a side elevation of a portion of the trough;

Figure 3 is a section on line 3-3 of Figure 2; and

F igLlTGl is a section on lined-4 of Figure 2.

Referring now to. the accompanying drawing 1. designatesa base which maybe of cast .iron or-similar material; .2 isv a connecting link which maylie-embedded permanently within the base'l or. may be simply passedthrough an aperture therein; 3 designatesithe sides. of the trough whichmay be of cast iron, boiler plate or other suitable material. The sideplates 3 are provided with apertures 4, through which the ends of thelink 2 may be passed after which wedges 5 may be forced in between theends of the links 2 and the plates 3 so as to fix those plates securelyin place on the base 1. A trough is thus formed which is very rugged,adapted to be easily assembled or dissembled.

The trough may be made in sections,in one of which the side plates 3 maybe allowed to extend beyond the base 1, and in the other, the base 1 isallowed to extend beyond the side plates so as to form a dovetail jointas shown at 6 in Figure 1.

The upper end 7 of the trough, which should be first lined withrefractory material 8, may be placed adjacent the iron notch of thefurnace or under the discharge opening of the ladle so as to receive themetal therefrom. The lower or discharge end 9 may be placed adjacent themolds which are indicated in Figure 1 by the dotted lines 10. Thesemolds may be arranged as a series of individual units mounted on aconveyor, which may be made to pass underneath the end 9 of the troughin such a way that the trough will discharge into and fill said molds.The trough, as a whole, should of course be given a sufli cient inclineto cause the metal to run freely from the end 7 to the end 9 and todischarge into the molds.

If the trough should become choked by the solidification of metal, slagor the like, it is an easy matter to dissemble the trough transverselyby removing the wedges 5 and knocking off the side plates 3 after whichthe obstruction may be removed with hammers or other means.

It will be seen that the invention accomplishes its objects. A trough isprovided which is adapted to convey molten metal in a convenient mannerfrom the source of supply to the place of utilization, It is adapted tobe easily dissembled so as to be out of the Way to make room for otheroperations and is adapted to be quickly and easily cleared ofobstructions.

It is obvious that various changes may be made in the details ofconstruction Without departing from the spirit of thisinvention; it is,therefore, to be understood that this invention is not to be limited tothe specific details shown and described.

Having thus described the invention, What is claimed is:

1. A trough for conducting molten metal, comprising, a base, a pair ofdetachable side members, and means for connecting J said base and saidmembers.

2. A trough for conducting molten metal, comprising, a base, a pair ofdetachable side members, and a'link adapted to connect said base andsaid members. i Y

3. A trough for conductingmolten metal, comprising, a base, a pair ofdetachable side members, and a link embedded in said base and adapted toconnect said base and said members.

and said members, apertures in said mem-.

bers adapted to engage said link, and means engaging said llnk adaptedto secure sald members in place.

6. A trough for conducting molten metal, 1

comprising, a base, a pair of detachable side members, a link adapted toconnect said base and said members,apertureg in said members adapted toengage said link, and a Wedge engaging said link adapted to secure saidmembers in place.

In testimony whereof I a'ffix my signature this 16 day of July, 1920.-

ROBERT AQBAGNELL.
